At
the end of this course the student should be able to understand the vectorial
and scalar representation of forces and moments, static equilibrium of
particles and rigid bodies both in two dimensions and also in three dimensions.
Further, he should understand the principle of work and energy. He should be
able to comprehend the effect of friction on equilibrium. He should be able to
understand the laws of motion, the kinematics of motion and the
interrelationship. He should also be able to write the dynamic equilibrium equation.
All these should be achieved both conceptually and through solved examples.

and their reactions – requirements of stable equilibrium – Moments and Couples
– Moment of a force about a point and about an axis – Vectorial representation
of moments and couples – Scalar components of a moment – Varignon’s theorem –
